Dear all,

I have qPCR data obtained with Fluidigm biomark array 96*96 with HTqPCR package (it's not digital PCR). I have n.features=78 (including 17 duplicated genes) and n.data=84 (30 duplicated samples, 5 duplicated points (standard curve for efficiency), 1 duplicated calibrator sample, and 4 single samples).

I want to analyze my data by taking into account duplicates but failed. I tried several things including changeCtLayout without success. Any help will be greatly appreciate.

Here are my code

Regards

Please not that I truncated the order content for easy viewing (so my order data contains 84 names).
